A folding light tower is provided that utilizes a 4-bar linkage mechanism which enables full vertical extension of the tower with the use of one actuator. The exemplary tower generally includes a base, a lower lift arm, and an upper lift arm. Spring elements are used near the rotating joints of the lower lift arm and upper lift arm of the tower. The spring elements act to preload the joints and help to remove play and movement when the tower is unfolded/during the vertical extension process. 一种折叠灯塔，设置为利用四杆连接机构，使用一个致动器使塔完全竖直的延伸。该示例性塔总体上包括基部、下提升臂和上提升臂。在塔的下提升臂和上提升臂的旋转接合部附近使用弹簧元件。该弹簧元件起到向接合部预加载的作用并在塔展开时/在竖直延伸过程期间有助于消除游隙和移动。
